It's a tough call to try to decide which Dickens book to hunt down all the real-life London locations for. Do you go with Little Dorrit and focus on the Marshalsea? Great Expectations? The Old Curiosity Shop? Oliver Twist? In the end we went for Our Mutual Friend, which switches between the watermen of Limehouse, the legal men of the City and wealth of the West End.
We've photographed some of the mentioned locations, many of which would be unrecognisable to Dickens today, and mapped them and the others. We've given the chapter numbers so you can look up the references yourself, should you be so inclined. (Warning: includes the odd spoiler.) Thanks to Gary Kinsman from the Londonist Flickr pool for the photo of the Maiden Lane Estate.
If you want to know about the locations of Dickens's books, the Our Mutual Friends project has six walks you can follow yourself or read about other authors' experiences of them.
